4. Racehorse Regal Monarch has been put down following a horror Melbourne Cup fall.

Regal Monarch, the horse that fell during race four on Melbourne Cup day, has been euthanised.

The horse was taken to Werribee Veterinary Hospital after the fall at Flemington on Tuesday, but could not be saved, said Racing Victoria’s chief vet Grace Forbes, according to AAP.

“It is with sadness that we can confirm that the horse has been humanely euthanised on veterinary advice as a result of the injuries sustained,” she said.

“Our sympathies are extended at this time to the owners of Regal Monarch, trainer Chris Waller, and his staff who cared deeply for their horse and are naturally devastated by their loss.”

Jockey Joao Moreira was cleared of serious injury but was unable to ride in the main race.

Activist groups including the People for the Ethical Treatment of Animals and the Coalition for the Protection of Racehorses are outraged, demanding reforms in the industry.

“It’s time for the racing industry to ban the whip and phase out two-year-old racing so that racehorses aren’t overworked and over-exerted,” Coalition for the Protection of Racehorses campiagn director Elio Celotto said in a statement.

6. Teen with “unnatural interest” in death sentenced to 21 years behind bars for the stabbing death of her own grandfather.

A young Queensland woman, with an “unnatural interest” in seeing people die, has been jailed for at least 21 years for the stabbing murder of her grandfather amid a plot to steal his life savings, AAP reports.

Brittney Jade Dwyer stabbed 81-year-old Robert Whitwell four times, then paused to do the dishes, as she waited for him to die at his Adelaide home.

Just 19 at the time, she had driven to Adelaide from Brisbane with her 21-year-old friend Bernadette Burns in August last year with the intention of robbing her grandfather of more than $100,000 he kept stashed in his backyard shed.

The pair pleaded guilty to murder, with Burns jailed for at least 13 years and six months for her part in the killing.

Sentencing the women in the Supreme Court on Tuesday, Justice Kevin Nicholson described Dwyer’s offending as evil and abhorrent and she remained a danger to the community.

The judge said she was motivated by greed and an “unnatural interest with violence and with seeing people die”.

When they arrived in Adelaide in February, the killers went to Mr Whitwell’s northern suburbs home.

Mr Whitwell’s body was found slumped in a chair three days later.

Justice Nicholson detailed Dwyer’s problems with drug and alcohol abuse and said she had been diagnosed with a borderline personality disorder along with anti-social traits and problems with rage.

He said the killing was a tragedy on two fronts.

“The very same people who have been badly damaged by the sudden and violent end to the life of Mr Whitwell are simply shattered by the fact that it was such a close member of the family, you Miss Dwyer, who so callously and brutally murdered him,” he said.
